Importance of chemical oxygen demand
WitrynaChemical Oxygen Demand (COD) COD is an indirect measure of the total organic matter widely used for wastewater monitoring, design and operation of STPs. It consists of the amount of oxygen required for the organic matter to be oxidized by a chemical oxidant (usually potassium dichromate in acid medium). The sample is digested for 2 … WitrynaBiochemical Oxygen Demand (BOD) The BOD is an important parameter for assessing water quality. It deals with the amount of oxygen consumption (mg O 2 L − 1) by aerobic biological organisms to oxidize organic compounds. Sewage with high BOD can cause a decrease in oxygen of receiving waters, which in turn can cause the …
